Answer:

Gas

Explanation:

The properties of the three states of matter are:

solid : fixed shape, fixed volume, high density as the intermolecular forces are strong and the particles cannot move here there. Only vibrations are possible.

Liquid: Fixed volume but shape depends upon the container, density lower than solid but higher than air.

Gas: Not fixed volume and not fixed shape also. The density is least among the three states of matter. There are leas strong force of interactions between molecules. the thermal energy is highest among the three states of matter.

Thus answer is gas.

A 1.250-g sample of benzoic acid, C7H6O2, was placed in a combustion bomb. The bomb was filled with an excess of oxygen at high
Degger [83]

Answer:

3224 kJ/mol

Explanation:

The combustion of benzoic acid occurs as follows:

C₇H₆O₂ + 13/2O₂ → 7CO₂ + 3H₂O + dE

The change in temperature in the reaction is the change due the energy released, that is:

3.256K * (10.134kJ / K) = 33.00kJ are released when 1.250g reacts

To find the heat released per mole we have to find the moles of benzoic acid:

<em>Moles benzoic acid -Molar mass: 122.12g/mol-:</em>

1.250g * (1mol / 122.12g) = 0.0102 moles

<em />

The dE combustion per mole of benzoic acid is:

33.00kJ / 0.0102moles =

<em>3224 kJ/mol </em>
